Pressure drop analysis for optimum inside-casing gravel pack design
A computer simulation program is developed to evaluate the productivity of inside-casing gravel packs. The assumptions are that perforations are treated as small wedges and gravel is assumed to fill the perforation and the casing-screen annulus. A three-dimensional, finite-difference model is develo...

A computer simulation program is developed to evaluate the productivity of inside-casing gravel packs.
